All the hate this anime and manga get

First off I apologize if this topic has been done to death but I'm a brand new fan of this series. I only started watching this anime 2 weeks ago and have caught up with the new season and everytime I see comments or discussions about it it's only mockery or hate. Even on the r/anime subreddit people seem to honestly be hate watching it. The other day I saw a tweet about barnes and noble shutting down and the poster made sure to point out that rent a girlfriend manga was fully stocked. I just don't understand since this show is really well animated, has great voice acting (Sora Amamiya?! Rie Takahashi?! Aoi Yūki?!) has moments that make you tear up and make you laugh (I crack up everytime Ruka is on the screen for how ridiculous she is) My point being I feel like this series should be beloved and not the target of endless mockery. Btw does anyone know how many chapters season 5 will cover? I really want to read the manga after
